A4 M4+BLDC cant arm one esc

[brat002]

Hi all.
I am building new quad-frame with M4 board+BLDC expansion board. After all wires was correctly connected and firmware was flashed i started tests. One motor+Kiss ESC 30a cant arm and spin. I tried to connect this motor in other ESC ports - it doe snot arm in any port. Although servo tester and receiver(when i connect wire from esc directly to PWM output) spins this motor.

What is wrong?

Yes.
MOT_ARM 975
MOT_START 1150
MOT_MAX 1832
MOT_MIN 1148

This problem affects only one ESC+motor.

All ESC`s from one batch and works pretty good with servo tester.

Yep. All ESCs calibrated.

attached some logs and params file.
I cant solve this problem.

I recalibrated ESCs with Mennos firmware. Nothing changed.

Today I performed some experiment. I soldered signal wire to backup pad on Kiss ESC and now it works. Very strange...

Glad you found out!

So it looks like the KISS is having troubles on the primary PWM input. Strange...
Maybe you should send a message to Flyduino, so Felix can get the info.

I cant take off. Frame has large oscilations, that can not be supressed with pid tuning. Does BLDC expansion board compatible with mennos firmware?
